Hence there To absorb the energy of the blot7 enjnot store it, the

or resilient. lf it ie inelastic, but not yield-v ing, then some of the energy of the blow will be stored inepringin7 the type-ber o? some of the connecting-linie, end then when tbe elasticity of tbeee parte returns them to their naturel form the type-ber will beve been thrown forward. o'

My vinvention consiste in providing en illelestio'or 'iou-resilient yielding ebtmeot for the type-bers to strike egeiaet. This ebutment consists of the cushion l. end its support 2. The essentiel ert oi' the device, however, is the cueliioo. n Fig. 3 tbe cushion l, the supporting-abutment 2, and the upper enfl of the type-b`er 3 ere shown, on eirenlerged scale, so es to moie clearly illustrate tbe oonstruction of the oushion. The cushion. here io. illustrated oonsiete oi e, casing or sheetli teriitl enel llin'f mede of granulated or 'otherwise inelywloivided meter-fiel. .l lieve found that e very ood materiel for the sheath is thin bucks (in end for the lillin smell shot about tliree or four hundredths o an inch in diameter. Many other forms of inel -riividefl materiel cenhbeused, suclios een glass beads, or balls, pulverizecl lime, chalk, small seeds, Sco. Seeds are not desir able, es thcy'will disintegrate after being struck e eater. or lese number of blows, Pulveiize materiels are liable to ceke, and send is objectionable, es in the event olt leekm ing through the sheath it might fet into the Workin parte of the machine encinweer them out. the construction o? the cushion, es shown in Fig. 3, is considered, it willbe seen tliet when the ty e-ber 3 strikeset the bells that form tbe til in will be disolocod, sind 'thus the energyo t 1e blow will e absorbed in imparting motion to these balls. When ollthe energy of the blow has been absorbed by tbe movement of the bells tliet constitute thelilling, the ty e-bor will come to o statte 'of rest, and it wil not rebound because there will be no stored-up energy. to send it for? ward, To make the cushion l es perfect in Actionee possible, the sheath must be of soft materiel and as inelastic als can be obtained, for it it istif and, decidedly elastic-it will store some of the energy of the blow, and thus cause the ty e-bar to rebound to o slight extent. ltis a sonecesserythat the filling of the tielee een out ol piece with little cueliioe. be ci suoli e atmet-lite til-et its ,oar-

A better idee of the con strction shown in Figs. fl mol 5 een be lieti from Fig. 6, Weich is o erosseectioii oi the tiret ligure on line B .B und ofthe seeoild on line A A.

I do not herein specifically eleim tho comn pertinente running longitudinally oi tbe peti or parallel with the sides thereof, but lieve elected Ato claim herein, broadly, the idee of having tlieee compartments ruiming et en one glo to the typo-bars and specifically the idee ot lim/ieg them :it en :ingle to the length of the parl.' 'llio letter form may be 'used in itil forme oi' tyefwritors, whereas the former le useful principally in circuler type-baskets. The ell'ect of both of 'tlleee forms is to pro-- duce zi .md with o lluted surlece, Wllicli especially advantageous in tvpepmi herring tbe inherent qualities of yielding and ,empresilienoy, in that it imtles tbe yielding of Athe pad more responsive to thev type-bor, omi while meiiltuining the breadth oi support for the typo'ber brings less'ot the materiel in Contact therewith, end therefore ioclitt-,tes eliminating the resilient effect of the oeil.

The type-bers es ordinarily mame llevo sharp edges, :is shown. in Fig. 7 at 'With the pode commonly used there is no objec tion to the sharp corners, but with the cushion here described there is, as the edges are liable to cut through the sheath, and thus allow the lling to escape. On this account I prefer to make the type-bar along the portion that strikes the cushion with rounded corners, as indicated on .bar 4 of this figure, o r

else I make them curved, as in Fi 8, or senn- -to its use when located in the position here shown, but claim it in any position in which the design of the machine on which it is used circular, as in Fig. 9. In these rawings the abutment and cushion are shown in position tobe struck by the upper end of the type-bar but it can be readily seen that this position is not the only one that will met the re uire- ,'ments. In fact, the abutment might be p aced so as to be struck by a projection from the type-bar provided just for that purpose, or it might even be placed so as to be struck by the key-lever 7 instead of the bar 3. As my invention is applicable to any form of typewriter using type-bars, I do not limit myself may require it to be placed. My invention consists 1n providing an inelastic and yield- "ing cushion to receive the impact of the blow struck by the type-bars on the'return stroke, and therefore is not limited either in on the return stroke, consistin ci a sheathv of sof flexible material, and a fil ing of inelyf divid d material, in rounded form. 1

2. A type-bar pad, having in its structure the inherent qua ities Aof yielding and non,-v resiliency and constructed in uted form.-

3. The combination of a cushionlocated to receive the im act of the ty'peliar's Ion their return stroke, ormed cfa sheath and a filling yielding bylateral displacement, and .on abutment shaped to receive said cushion ,and sup- A port it along the sides.

4. The combination of a yielding inelastic cushion to support the ty e-bars in their normal position, consisting o `a sheath of flexible material, anilla filling of finely-divided material, and an abutment shaped to receive and hdllllsaid cushion. .i

5. The combination of a yielding inelastic cusliion consisting of a sheath arranged to divide said cushion into compartments, these compantments being filled with a finel divided'material, yielding by lateral disp accment; and an abutment fastened to the frame of the machine, 'and provided with a groove or depression tohold the cushion in its I proper position.

6. A yieldin inelastic cushion to receive the impact of t e type-bars, comprising compartments made of flexible material, lilled -With a finely-divided substance.

7. A yieldin inelastic cushion to receive the impact ofA t e t e-'bars, consisting of an inclosing sheath divided into compartments filled with a finely-divided material the line of division between the compartments running at an angle to the direction in which the filling tends'to gravitate.

kln a'type-Writer, a yielding inelastic cushion for arresting the type-bars in normal position, constructed of an inclosing sheath and a filling of i'inely-divided material; the sheath being formed in a plurality of compartments, the lines o f division between which compartments extend at an angle to the length ofthe cushion.

9. In a type-Writer, a yielding inelastic cushion for arresting the typebars in normal position, constructed of an inclosing sheath and a iilling of finely-divided material; the sheath being formed in a lurality of compartments the lines of t ivision between which compartments extend at an angle to.

the len o'thandvto the transverse dimension of the cushion.

v 10. Ina type-writer, a yielding inelastic cushion to receive the impact of the type-bars on their return stroke, consisting of a sheath of flexible material constructed to form compartments ruiming diagonally across the face of the cushion, and a idling of finely-.divided material in these compartments.

11. The combination of a. typc-write'r-ke cushion constructed with a filling to absor the energy of the blow yieldin f by lateral displacement when struck by t ie typebars,

rperly located to receive the impact of said liars; an abutment shaped to receive' and hold the cushion, and the typebars constructed with rounded surfaces or corners along the portion that strikes the cushion,

12. The combination of'a yielding non resilient cushion to support type-bars in their normal pcsition, consistingof ,a sheath oi" suitable flexible material, and a filling ol" finely-divided material; an. abutment secured to the'i'rame of the macl inc and adapted to receive and hold the cussiion; type-bars arranged to strike and rest against the cushion; and the operating key-levers acting under a suitable return influence, to return the type- IOO iig

bars, to their normal'position against the y cushion.
